Unformatted text preview: line up along different spindle fibers, in meiosis they line up side by side (). The chromosomes then undergo a process called genetic reassortment, in which a piece of chromosome from the maternal homologous pair crosses over with a piece of chromosome from the paternal homologous pair. This crossover occurs after the two sets of homologous pairs (maternal and paternal) become physically linked through the formation of a chiasma. Figure %: Genetic reassortment It is known that proteins are responsible for holding the chromosomes in their appropriate alignment, but the details of the mechanism are not yet fully understood. The crossover of chromosomes in genetic reassortment creates new DNA combinations. In other words, the genetic reassortment gives rise to a unique genetic make-up that results in some of the genetic variation found in sexual reproduction....
